  Do you know why he didn't just use Arabic characters? Based on a brief survey of the Arabic Wikipedia, it looks like Latin letters are standard for variables in math these days, but what was the reason for using non-Arabic characters back then?

    It is odd, given that other scientists did use Arabic characters to notate their diagrams (notably, Al-khwarizmi and Ibn Al-Haytham). Perhaps it's because of his roots.
